Comparison and Evaluation of Water Occupancy Rates of the Kılıçkaya Dam Lake (Turkey) between 2010-2021

Abstract

This study was carried out in Kılıçkaya Dam Lake in northeastern Turkey. Kılıçkaya Dam is a dam built between 1980-1989 to generate energy on Kelkit Stream. With this study, the water occupancy rates of Kılıçkaya Dam Lake, which has a proportionally large area, between the years 2010-2021 were compared and evaluated. If a general conclusion is drawn for Kılıçkaya Dam Lake, it has been determined that the water occupancy rates between the years 2010-2021 varied between 18.40 and 56.80 percent. The slope line of the water occupancy rates obtained in this study is downward. The results showed that the water occupancy rates in Kılıçkaya Dam Lake have a decreasing trend on an annual basis. When the average of the water occupancy rates between 2010-2021 is evaluated, the water occupancy rate values in Kılıçkaya Dam Lake indicate drought. The results obtained will be of great benefit to various users and decision makers in terms of their future planning within the framework of a comprehensive and large-scale drought management plan that is proposed to be prepared for the Kılıçkaya Dam Lake.
